Hi,

I tried to use the example in New-UDStepper to create a flow for setting the expiration date for consultant users.
Stepper - PowerShell Universal

But instead of have a New-UDTextbox with the -value parameter, i want to use a New-UDTable and New-UDDatePicker instead.

New-UDApp -Title 'PowerShell Universal' -Content {
    New-UDStepper -Steps {
        New-UDStep -OnLoad {
            New-UDGrid -Container -Content {
                New-UDGrid -ExtraSmallSize 5 -Content {
                    New-UDCard -Content {
                        $UsersToSelectFrom = Get-Aduser -filter "SamAccountName -like 'cons_*'" -Properties DisplayName,AccountExpirationDate
                        $Columns = @(
                            New-UDTableColumn -Property UserPrincipalName -Hidden
                            New-UDTableColumn -Property SamAccountName -Title "Initials" -ShowSort -ShowFilter -DefaultSortColumn
                            New-UDTableColumn -Property DisplayName -Title "Display Name" -ShowSort -ShowFilter
                            New-UDTableColumn -Property AccountExpirationDate -Title "Expiration Date" -ShowSort
                            New-UDTableColumn -Property Enabled -Title "Enabled" -ShowSort
                            New-UDTableColumn -Property SelectedADObject -Render {
                                New-UDButton -Text "Select" -OnClick {
                                    Show-UDToast $EventData.SamAccountName
                                    Set-UDElement -Id 'SelectedConsUser' -Content {$EventData.SamAccountName}
                                } -ShowLoading
                            }
                        )
                        New-UDTable -Columns $Columns -Data $UsersToSelectFrom -ShowSort -ShowFilter -ShowPagination -PageSize 8 -Dense -DisablePageSizeAll
                        #New-UDTextbox -Id 'txtStep1' -Value $EventData.Context.txtStep1
                    }
                }
            }
            
            
            
        } -Label "Select user"

        New-UDStep -OnLoad {
            New-UDGrid -Container -Content {
                New-UDGrid -ExtraSmallSize 5 -Content {
                    New-UDCard -Content {
                        New-UDDatePicker -OnChange {
                            Show-UDToast -Message $body
                        }
                    }
                }
            }
            
            New-UDTextbox -Id 'txtStep2' -Value $EventData.Context.txtStep2
        } -Label "Select new expiration data"

    } -OnFinish {
        New-UDTypography -Text 'Nice! You did it!' -Variant h3
        New-UDElement -Tag 'div' -Id 'result' -Content {
            $(Get-UDElement -Id 'SelectedConsUser').Value | Out-File C:\Temp\SelectedConsUser.txt
            $f = $body | ConvertFrom-Json 
            $f.context | Out-File C:\Temp\StepBody.txt 
        }
    }
}

How do i save the value from the steps (SamAccountName and the date) for use in the final block?
